Purchase PCB detection tools and always detect the height of the circuit board.

Measuring the circuit board with a caliper or not referring to the specification sometimes leads to errors in milling results. I suggest using the PCB detection tool. Use the drill loader menu and follow the prompts to detect the thickness of the circuit board before cutting. Remove the detection tool before cutting.

With the help of a circuit board guide rail and double-sided tape, the circuit board is completely fixed in place.

The circuit board guide rail (bracket) is a very convenient tool, which can help the machine locate the position that needs to be cut. In the milling process, you can use the inverted large cutting tool to position the tool and then click "position". If the circuit board is not completely fixed on the cutting disc with adhesive tape, the drill bit will move the circuit board back and forth when cutting begins. Before sticking the new circuit board with adhesive tape, make sure there are no fragments on the waste board. This positioning function may be different for different milling machines.

Measure repeatedly before cutting to ensure accuracy.

Before milling, ensure that the pad size and circuit board layout size are accurate. Although milling and using circuit boards are free, and the cost of cutting new circuit boards is relatively low, in this case, the cost of re-milling professional circuit boards is much higher.

Check the drill bit before cutting.

Before cutting the circuit board, make sure that the appearance of the drill bit is not damaged or worn. The drilling depth of the damaged or worn drill bit may be deeper than the expected position, and even damage the structure around the drilling, resulting in the re-cutting of the entire circuit board.

The process of cutting circuit boards and the general sequence of steps should be followed.

1. the Fixed circuit board
2. Connect the bracket and "position"
3. Choose whether to use custom size circuit boards or standard single/double-sided circuit, boards
4. Load the complete plan: front side, rear side, boundary, and borehole
5. Install the copper plate with double-sided tape
6. Replace the appropriate milling tool (first select the wiring on one side) and fix its position to ensure that the tool can touch the bottom of the waste plate, not the copper plate or the cut object
7. Use the "drill loader" menu to detect the height of the circuit board
8. Start milling wiring and replace the drill bit when necessary (if a drill bit is not applicable, the milling machine software will display a prompt)
9. Milling through holes with recommended drill bits
10. Finally, use a larger tool to mill the boundary layer (boundary)

Cutting a double-sided circuit board can also follow the above steps, but it is recommended to mill the wiring on one side and then the wiring, through holes and boundaries on the other side. If the drill bit cannot completely pass through the circuit board for drilling, the circuit board can be turned over and cut again, but it will be easier to poke out the rest with the same drill bit used in tool cutting because it can drill out the rest anyway.

Ensure that the scrap board and the loaded copper board are clean.

If the scrap plate or copper plate is not clean and there is material on it, the measured height may be affected, resulting in errors in milling. Clean the machine with a vacuum cleaner after each use.
